Principles of
Electronic
Communication
Systems

A continuing goal of this latest revision is to increase the emphasis on the system
level understanding of wireless, networking, and other communications technologies.
Because of the heavy integration of communications circuits today, the engineer and the
technician now work more with printed circuit boards, modules, plug-in cards, and equip-
ment rather than component level circuits. As a result, older obsolete circuits have been
removed from this text and replaced with more integrated circuits and block diagram level
analysis. Modern communications engineers and technicians work with specii cations and
standards and spend their time testing, measuring, installing, and troubleshooting. This
edition moves in that direction. Detailed circuit analysis is still included in selected areas
where it proves useful in understanding the concepts and issues in current equipment.
